Air-to-Air Heat Exchanger Guides for Engineers & Specifiers

In-depth, practical articles on how air-to-air heat exchangers recover energy, the trade-offs between plate, rotary and heat-pipe designs, and how to size and select the right unit. All content is written to help you specify with confidence.

Start with the fundamentals

An air-to-air heat exchanger transfers heat between two air streams without mixing them. It is the core component behind energy recovery ventilation, industrial waste-heat recovery and free cooling. The articles below walk through the technology, the selection rules, and real application examples.
